IMPROVEMENT IN LAMP-'BURNERS.

The Schedule referred to in thele Letters .Patent and making part of the lame.

Figure l is an elevation onside View of a'lampburner embodying my inventiom Figure '2 is a longitudinal section of the same. .Figure 3 is a transverse section of the'hurners, taken through the openings for the introduction of burning-fluid, when the wick-tube is pressed down.

A is the wick-tube, projecting from the cylindrical guide a, to which it is attached near its upper end.

The lower end of the guide a has secured to it one end of the coil-spring 0, this spring resting upon the bottom of the body B of the burner, which is perforated.

wick tube, for closing the openings in the bottom "of the body B. Beneath the opening cin the body B is the annular oil-cup d.

b is an opening opposite c in the cylindrical guide a.

E is a perforated plate, above which the superior end of the wick-tube extends when thelamp is ready for use. 7 f

\Vhen it becomes necessary to trim the wick of the lamp, the guide a. is pressed down-upon the spring 0, to such an extent that the upper end of the wicktube is beneath the perforated plate E, exposing thewiek, which may be cut to the requisite length and shape vithout the delay usual in the same ope ation D is a valve-plate, located on the inner end of the in lamps wherein thewick-tube is secured to the body of the burner, making it necessary to remove the glass chimney before the operation can 'be peformed.

While the wick-tube is pressed down the openings 1) and c in the wick-tubeguide and body B of the burner areadjacent, which permits the introduction of the nozzle of the fluid-can to supply the lamp with burning-fluid when it needsreplenishing without removing the b'nrnerfrom thezlamp by unscrewing the body of the burner B thereiioih.\

When the lamp has beenput' in complete order, without soiling more than the thumb and finger, the wicktube is freed, and the action of the spring 0 brings the valve D up against the bottom of the body B of the burner, ,by whichescape of the oil or burningfluid is prei'entetb I acknowledgev that a sliding wick-tube is not new; nor the openings for the purposes mentioned, either; but

What I claim as my invention is-- 1. The combination of the sliding wicktube A and spiral spring 0, as herein set forth.

2. The valve-plate D-, sliding wick-tube A, in combination with guide a, body B, and openings b and a, when arranged in the manner and for the purpose herein shown and specified.

3. The wick-tube A, valve D, and spring 0, arraugedand operating substantially inthemanner and for the purpose set forth. I

4. The combination and arrangement of the sliding wick-tube A, valve D, spring 0, guide a, and body B,

when constructed substantially in the manner herein shown, and for the purpose specified.
